A renewal letter lands, or your contract end date quietly approaches, and you have a decision to make. The good news is that there are only three options, and once you understand what each one really costs, the right move is usually clear.
First, know your dates
Everything starts with two dates: when your current contract ends, and when your renewal window opens. Most suppliers let you agree a new contract up to 12 months ahead of the end date, which gives you plenty of room to plan. Your latest bill shows the end date; if you cannot find it, your supplier or a broker can confirm it.
Knowing these dates matters because the costliest outcome, doing nothing, happens by default when they slip past unnoticed.
Option 1: Do nothing (and why it is the costliest)
If your contract ends and you have not agreed a new one, you do not simply keep your old rate. You move onto out-of-contract or deemed rates, the supplier's default pricing for customers without a contract. These are among the highest rates a supplier charges, precisely because nothing has been negotiated.
Some contracts can also roll over automatically into a fresh term that you did not choose. Either way, inaction is rarely neutral. It almost always means paying more than you need to, sometimes for months before anyone notices.
Option 2: Renew with your current supplier
Staying put is the path of least resistance, and there is nothing wrong with loyalty if the price is right. The catch is that a renewal offer is a starting point, not a guaranteed best price. Suppliers know that renewing is convenient, and convenience is not always priced in your favour.
If you do want to stay, treat their offer as one quote among several. Compare it against what the wider market would give you for the same usage. If it stacks up, renew with confidence. If it does not, you now have the evidence to negotiate or move.
Option 3: Switch (and how to make it painless)
Switching has a reputation for hassle that it no longer deserves. Your supply never goes off, the same wires and pipes deliver your energy, and your new supplier handles the changeover with the old one. The only real work is comparing the market and signing the right contract, which a whole-of-market broker can do for you.
If you are weighing this up, our step-by-step guide on how to switch business energy supplier walks through exactly what to gather and what happens next. The headline: a switch agreed in your renewal window simply starts the day your current contract ends, with no gap and no disruption.
When to act
Three to six months before your end date is the sweet spot. Early enough to compare calmly and lock in a price you are happy with, late enough that quotes reflect current market conditions. Leaving it to the final week forces a rushed decision, and missing the date altogether drops you onto deemed rates. Put a reminder in the diary the moment you sign any contract, dated a few months before it ends.
A quick checklist
- Find your contract end date and renewal window.
- Note whether your contract can roll over automatically.
- Gather your usage (kWh) and meter numbers.
- Get your supplier's renewal offer in writing.
- Compare it against the wider market before deciding.
- Agree your next contract to start the day this one ends.
Whether you renew or switch matters less than not drifting onto deemed rates by accident.
